To all whom 2'2 may concern:

Be it known that J 011x J. BAUER, a citizen of the United States. residing at Baltimore city, in the State of lllaryland, has invented certain new and useful Improvements in Jar-Capping Machines, of which the following is a specification.

This invention relates plying jar caps. for domestic use in cap to to machines for ap- Itis primarily intended applying a large metallic glass jars, such as that shown and in patent issued to Edward D. Schmitt, Number 1,075,125, dated October '7, 1913, which is a cap of comparatively hard metal designed to have its flange permanently flexed into locking engagement with an angular shoulder on a glass jar.

The invention about to be described does not reside in the sealing head, and it would be understood that a sealing head of any approved construction adapted to properly seat and lock the cap on the jar may be empl yed, but preferably there is employed a sealing head embodying the construction shown in patent to A. R. Bethel, Number 1,305,765, dated June 3, 1919. Since as above stated, the uses of this machine are domestic uses, it is important that the machine be sim le in construction, durable and be producible at a figure readily within the reach of the householder. The primary objects of the invention are to produce a simple, inexpensive and efficient device, and one that may be folded in such way as to make a compact package for shipment, and in such a way as to enable it to be inexpensively shipped.

Other objects and advantages will become apparent in the course of the following description.

Figure 1 is a perspective view of the machine in position for operation, there being shown a jar in sealing position below the head.

Fig. 2 is a top plan view of the machine with the parts folded into convenient form for packing for shipment.

Fig. 3 is a section through the base in advance of the standard showing the manner or" connecting the standard pivotally with the base.

Fig. 4 is a similar view with extension members applied to the base, and embracing the arms of the standard for lengthening the standard to adapt the machine for Specification of Letters Patent.

sealing receptacles higher in Figs. 1 and 3, and

Fig. 5 is a detail perspective of one of the extension members.

Referring to the drawings, the numeral 1 designates the base of the machine. This is preferably constructed of wood. It is provided near one end with a transverse bore 2 into which is fitted a metallic bushing 3, which may be merely a tube of requisite length so that its ends will be flush with the sides of the base, or the bore may be provided at its ends with short bushings, as may be preferred. The numeral 4 designates the standard which is yoke-shaped and each leg 5 of the standard is provided at its lower end with short inturned portions 6, which portions extend into, and pivot in the bushing 3. To the upper trans verse part 7 of the standard is pivotally secured the manually operated pressure applying lever 8. This lever is bifurcated as indicated at 9, and extended and shaped at its free end to form a grip portion 10. The numeral 11 designates the sealing head or capper which, as before stated, may be of any approved construction. In the con struetion shown, the head is provided centrally with a lug 12 which extends through the bifurcation of the lever, and it is provided with a hole 13, adapted to register with a similar hole 11, in the ends of the lever, and the capper is held suspended in the lever by a readily removable pin 15.

In some cases it may be desirable to extend the standard so as to raise the capping head to a greater distance above the base, and to this end I provide an ordinary rod 16, threaded at its opposite ends for the reception of nuts 17. This rod is adapted to extend through and beyond the bushing 3 on both sides of the base. The numeral 18 designates two identical extension members. Each member is provided at its upper end with a lateral extension or angle piece 19, recessed as indicated at 20, and they are also provided with a series of spaced aperatures 21. In extending the height of the standard, the arms 5 thereof are sprung apart withdrawing the portions 6 out of the bush ing. The rod 16 is then inserted, and each end of the rod extended through the bottom hole of each extension member, and the nuts put on. The portions 6 of t 1e standard are then inserted in any of the desired aperthan those shown 5 head suspended atures 21 with the side piece 5 of the standard extending through the recess 20. The nuts are then tightened until a rigid assemblage is accomplished. The machine is then ready to operate upon a receptacle of a height greater than that upon which it operates when the parts are in the position shown in Fig. 1.

However, it will be understood that by reason of the pivotal connection of the standard with the base as shown in Fig. 1, and regardless of the extension members, the machine will operate satisfactorily upon jars varying very considerably in height, it being only necessary to change slightly the position of the jar on the base, that is to say, by moving it to or from the pivotal point of the standard.

Since the machine is primarily adapted for capping jars of uniform size, I have indicated on the base by a circle, the proper location of the jar for eflicient capping. will be noted that by reason of the pivotal connection of the capper or sealing head with the pressure applying lever, a swinging action is possible which automatically centers the capper on the jar.

As shown in Fig. 2, when it is desired to fold the machine in compact form for shipment, the pin holding the capper in the bifurcation of the lever is removed, thus releasing the head which is placed upon the base near the end opposite that which it ordinarily occupies, and the lever is reattached to the capper after which, the ends of the standard are again sprung into the bushings when obviously all of the parts are securely held together.

The numeral 22 designates a notch or recess which is provided at the end of the base opposite the pivotal point of the standard, and this is adapted to receive the free end of the pressure applying lever when the machine is not in use to keep the sealing above the base.

lVhile I have shown a sealing head adaptt tending into the apertures ed for applying a large cap, it is obvious that there may be readily adapted to the bifurcated end of the pressure applying lever a head of smaller diameter to apply small caps to bottles if need be.

Claims:

1. In a capping machine, in combination, a suitable base, a standard pivotally secured to the base, a pressure applying lever pivoted to the standard, and a capper carried by the lever.

2. In a capping machine, in combination, a suitable base, a standard pivotally secured to the base and comprising a yoke-shaped member, a pressure applying lever pivotally connected with the upper part of the standard, and a sealing head pivotally secured to said lever.

8. In a capping machine, in combination, a suitable base having apertures therein, a yoke-shaped standard having portions exstandard is pivotally connected with the base, a pressure applying lever pivoted to the upper part of the standard, and a sealing head pivotally and detachably secured to said lever.

4. In a capping machine, in combination, a suitable base, a yoke-shaped standard formed of a single piece of spring metal, means for pivotally attaching the standard to the base, a'pressure applying lever pivoted to the upper part of the standard, and a sealing head carried by said lever.

5. In a capping machine, in combination, a suitable base, a standard pivotally connected with the base, means forvarying the height of the standard, a pressure applying lever secured to the standard, and a sealing head carried by the lever.

In testimony whereof I affix my signature in presence of two witnesses.
